Item 1C. Cybersecurity.

Item 1C. Cybersecurity Risk Management and Strategy Liberty Broadband s corporate level IT and cybersecurity functions are provided by Liberty as part of the services agreement described in Item 1. Business. Through the services agreement, we participate in Liberty s processes for assessing, identifying, and managing risks from cybersecurity threats at the corporate headquarters, as detailed below. GCI operates its own cybersecurity function with oversight from Liberty Broadband. Charter, an equity method affiliate, as a separate publicly traded company from Liberty Broadband, operates its own cybersecurity function. Oversight for Charter s cybersecurity functions rests with its board of directors and Audit Committee of which our Chief Executive Officer is a member. We are committed to protecting the security and integrity of our systems, networks, databases and applications and, as a result, have implemented processes designed to prevent, assess, identify, and manage material risks associated with cybersecurity threats. Cybersecurity risks are assessed as part of our enterprise risk assessment and risk management program and our cybersecurity risk management program is designed and assessed based on recognized frameworks, including the National Institute of Standards and Technology Cybersecurity Framework ( NIST CSF ). We rely on a multidisciplinary team, including our information security function, legal department, management, and third-party consultants, as described further below, to identify, assess, and manage cybersecurity threats and risks. We identify and assess risks from cybersecurity threats by monitoring and evaluating our threat environment and our risk profile using various methods including, using manual and automated tools such as vulnerability scanning software, monitoring existing and emerging cybersecurity threats, analyzing reports of threats and threat actors, conducting scans of the threat environment, evaluating our industry s risk profile, utilizing internal and external audits and assessments, and conducting threat and vulnerability assessments. I-56 Table of Contents To manage and mitigate material risks from cybersecurity threats to our information systems and data, we implement and maintain various technical, physical and organizational measures, processes and policies. These measures include risk assessments, incident detection and response, vulnerability management, disaster recovery and business continuity plans, internal controls within our IT, Security and other departments, encryption of data, network security controls, access controls, physical security, asset management, system monitoring, vendor risk management program, employee cybersecurity awareness and training, phishing tests, and penetration testing. Cybersecurity awareness training is also made available annually to our board of directors. In the event of a potential cybersecurity incident, or a series of related cybersecurity incidents, we have cybersecurity incident response frameworks in place at the corporate level and at GCI. These frameworks are a set of coordinated procedures and tasks that our incident response teams execute with the goal of ensuring timely and accurate identification, resolution and reporting of cybersecurity incidents both internally and externally, as necessary. To operate our businesses, we utilize certain third-party service providers to perform a variety of operational functions. We have implemented a third-party risk management program to evaluate the cybersecurity practices of higher risk vendors and vendors that encounter our systems or data. We additionally engage and retain third-party consultants, legal advisors and assessors to keep us appraised of emerging third-party risk, defense and mitigation strategies, and governance best practices. Impact of cybersecurity risks on business strategy, results of operations or financial condition As of the date of this Annual Report on Form 10-K, we are not aware of any risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. For additional information on our cybersecurity risks, see Risk Factors under the section entitled Cyberattacks or other network disruptions could have an adverse effect on our company and GCI s business" in Part I, Item 1A of this Annual Report on Form 10-K. Governance Role of the Board of Directors Our board of directors has overall responsibility for risk oversight and has delegated to the Audit Committee primary enterprise risk oversight responsibility, including privacy and cybersecurity risk exposures, policies and practices, the steps management takes to detect, monitor and mitigate such risks and the potential impact of those exposures on our business, financial results, operations and reputation. The Audit Committee receives quarterly updates on the enterprise risk management program, including cybersecurity risks and the initiatives undertaken to identify, assess and mitigate such risks. This cybersecurity reporting may include threat and incident reporting, vulnerability detection reporting, risk mitigation metrics, systems and security operations updates, employee education initiatives, and internal audit observations, if applicable. In addition to the efforts undertaken by the Audit Committee, the full board of directors regularly reviews matters relating to cybersecurity risk and cybersecurity risk management. Any material cybersecurity events would be brought to the attention of the full board of directors once the event is deemed material. We additionally use our incident response framework as part of the process we employ to keep our management and board of directors informed and to monitor the prevention, detection, mitigation, and remediation of cybersecurity incidents. Role of Management Through our services agreement with Liberty discussed in Item 1 of this 10-K, we have established a cross functional Information Security Steering Committee ( ISSC ) with executives from our Legal, Accounting, Internal Audit and Risk Management, Cybersecurity and Facilities departments. The ISSC has management oversight responsibility for assessing and managing technology and operational risk, including information security, fraud, vendor, data protection and privacy, business continuity and resilience, and cybersecurity risks at the corporate level and our subsidiaries. I-57 Table of Contents At GCI, there is an Enterprise Security Office ( ESO ), led by the Chief Information Security Officer ( CISO ), which is responsible for day-to-day management and oversight of subsidiary cybersecurity, including assessing, monitoring and mitigating cybersecurity risk. The CISO provides regular reporting to GCI executive management and the ISSC. Liberty Broadband has also established a Compliance Committee responsible for overseeing and monitoring all corporate compliance initiatives at GCI, including cybersecurity. The Compliance Committee is composed of members of Liberty Broadband s ISSC as well as GCI s executive leadership team, including the President & Chief Operating Officer, General Counsel, and Chief Financial Officer. The CISO reports periodically to the Compliance Committee on cybersecurity risks and initiatives as well as any cybersecurity events, as applicable. Our management team s experience includes a diverse background in telecom and other industries, with decades of experience in various aspects of cybersecurity. Liberty s Head of Cybersecurity has more than 25 years of cybersecurity and information technology experience and holds Certified Information Security Manager and Certified in Risk and Information System Control certifications. GCI s CISO has more than 20 years of experience and hold multiple certifications including Certified Information Security Systems Professional and Certified in Risk and Information System Control. Both have worked at a variety of companies, including large publicly traded companies, implementing and managing IT and cybersecurity programs and teams, developing tools and processes to protect internal networks, customer payment systems and telecommunications networks used by customers to transmit data.
